| titleOfInvention | Thermoplastic material, hollow capsule and preparation method and application thereof |
| abstract | The invention discloses a thermoplastic material, a hollow capsule, a preparation method and application thereof. The thermoplastic material comprises the following components in parts by weight: 30 parts of starch, 10-30 parts of gelatin, 30-40 parts of plasticizer, 5-10 parts of cross-linking agent and 10-15 parts of zinc salt. The invention also provides a preparation method of the hollow capsule, which comprises the following steps: and carrying out injection molding treatment on the thermoplastic material at 80-90 ℃ to obtain a hollow capsule blank, and then drying the hollow capsule blank to obtain the hollow capsule. The hollow capsule prepared by the invention has the advantage of relatively constant dissolution speed in different water temperature environments when being used for putting oil field chemicals, can be used for releasing various oil field chemicals such as gel breakers, solid acids and the like in a specific time period or a specific position underground, greatly reduces the using amount of the oil field chemicals, simplifies the construction procedure, and provides a new solution for oil and gas exploitation work. |
